A total of 174 subjects aged 18 to 24 were examined using the Greene-Vermillion index of dental deposit for the assessment of the oral cavity hygienic status. The intensity of chronic gingivitis was assessed using the PMA index modified by Parma. In all the patients dental deposit was removed using cotton cones formed on fine conical fissure bores fixed in angular tips. Phosphate cement powder was used as a abrasion material. In a month the patients were examined repeatedly. One session of a professional removal of the dental deposit was found sufficient to reduce the dental deposit index and the intensity of chronic gingivitis, this permitting a conclusion on the efficacy of this preventive method and recommending it for practice.
共有174名年龄在18至24岁之间的受试者接受了检查，使用格林 - 弗米利恩牙菌斑指数来评估口腔卫生状况。慢性牙龈炎的严重程度使用帕尔马修改后的PMA指数进行评估。在所有患者中，使用固定在角尖上的细锥形裂隙钻头上形成的棉锥去除牙菌斑。磷酸锌水门汀粉末用作研磨材料。一个月后对患者进行了复查。发现一次专业的牙菌斑清除足以降低牙菌斑指数和慢性牙龈炎的严重程度，由此可以得出该预防方法有效的结论，并推荐在实践中使用。
